In this video Paul Andersen explains that the angular momentum of a system will be conserved as long as there is no net external torque. Both point objects and extended objects are covered along with several examples.

In this video Paul Andersen explains how the kinetic energy gained by an object is equivalent to the work done on the object. The force on the object must act parallel or antiparallel to the motion of the object to do work. Several...

Mr. Andersen explains the basic quantities of motion. Demonstration videos and practice problems are also included. The difference between scalar and vector quantities is also discussed.

This content addresses a physics problem focused on the vertical motion of a thrown ball. It outlines how to determine both the time to reach maximum height and the maximum height achieved by the ball, by applying kinematic equations and...

This content outlines a two-phase approach to analyze the motion of a car that first accelerates from rest and then decelerates to a stop. It details how to calculate the time taken and distance covered in each phase, using kinematic...

Master motion under constant acceleration with clear derivations of the kinematic equations (v = v₀ + at, s = v₀t + ½at², etc.). Learn how to apply them to solve motion problems with intuitive visual aids and examples.

Acceleration is the rate of change in velocity over time. Acceleration can be calculated using the formula a=vf-vi/t. Acceleration can be positive, which means speeding up, negative which means slowing down and it can also be 0 which...
